We're dividing 815747 by 80 
We're looking to find how many times 80 goes into 815747.

On to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 80

Moving on to step 2:
80 goes into 81 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 80 from 81 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 80

On to step 3:
15 divided by 80 is 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 15, we get 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 80

Going ahead to step 4:
80 can be fit into 157 1 times, resulting in a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 101.0
If we take 80 away from 157, we end up with 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 80

Going ahead to step 5:
774 divided by 80 is 9 with a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 1019.0
Subtract 720 from 774 to get 54.
Append the next digit (7) from the dividend to 54 and continue with: 547 / 80

Advancing to step 6:
547 divided by 80 is 6 with a remainder of 67.
Write down 6 as next digit of the result. 
Result so far: 10196.0
The remainder is 67 after subtracting 480 from 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 7:
The number 80 fits into 670 8 times, leaving a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 10196.8
Deduct 640 from 670 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
80 can be fit into 300 3 times, resulting in a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 10196.83
Deduct 240 from 300 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 10196.837
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
400 divided by 80 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 10196.8375
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10196.8375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10196.8375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 10196.8375 with a remainder of 0.0.
